The hand groupings are valuable because they help you see, generally, which hands are good starters. They are problematic if you take the approach you appear to be taking, which is to say "I have a group 5 hand so I'm going to play it!" The texture of your game, how many players have already entered the pot, whether the pot has been raised when the action is on you, whether you think there will be a raise after you, whether you think you can steal the blinds if you open raise, etc., are all considerations when you make your decision whether to play or muck. In the case described above, with only one limper to me in the cutoff, I'd have folded 65s without a second thought. I hope this helps.
